RECORDING INSTRUMENT.

Specification of Letters Patent.

Patented Apr. 21, 1914.

Application filed L n-i126, 1913. Serial No. 763,850.

To all whom it may concern Be it known that I, OSCAR E. KRONE, a citizen of the United States, residing at Mapleton, in the county of Iron and State of Michigan, have invented certain new and useful Improvements in Recording Instruments, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to new and useful improvements in recording instruments and more particularly to a recording instrument for mines, the object of the invention being to provide a recording instrument which will correctly record the number of carloads or buckets of ore removed from the mine, and will also record the time that the hoisting mechanism is idle, recording the time the mechanism stops and the time that it starts again, so that the correct time of delay will be given.

Another object of the invention is to provide a recording instrument of the above character which will possess advantages in points of efficiency and durability, is inexpensive of manufacture and at the same time is simple in construction and operation.

With the above and other objects in view, this invention consists in the novel features of construct-ion and the combination and arrangement of parts to be hereinafter more fully described, pointed out in the claims and shown in the accompanying drawings, in which- Figure 1 is a front elevation of a recording instrument constructed in accordance with my invention. Fig. 2 is a transverse sectional view of the same. Fig. 3 is an enlarged transverse sectional view, illustrating the manner of operating the trip member.

Referring more particularly to the drawings 1 indicates the supporting frame having arranged therein a central member 2, upon which is rotatably mounted the circular plate 3. Arranged in front of the plate and connected thereto by means of the hook members 1 is a dial or chart 5. The plate 3 is mounted upon the outer end of the shaft 6, said shaft being rotated by means of suitable clock work mechanism arranged within the casing 7 at the rear of the supporting 1 frame 1. The dial or chart 5 is provided upon its outer face with a plurality of circularly arranged numerals ranging from 1 to 12, one set of numerals extending from the center at one side of the plate to the center at the opposite side of the plate and arranged between the numerals are the dashes which indicate the minutes of the hour while the numerals indicate the hour.

Pivotally mounted at the lower end of the frame 1 is a vertically disposed movable rod 9 upon the upper end of which is mounted a marker 10, said marker being provided with a suitable engaging point 11, which is supplied with ink from the body of the marker so that as the plate 3 rotates in the direction indicated by the arrow, the point 11 will readily mark upon the plate adjacent the periphery of the dial 5. The rod 9 is held in its operative position by means of a coil spring 12 which yieldably holds the rod 9 into engagement with the stop pin 13 carried by the central member 2. Pivotally secured to the rod 9 adjacent the upper end thereof is an actuating bar 1 1 which extends outwardly through an opening 15 in the outer edge of the frame 1 and the outer end of said bar is arranged beneath the indicator dial 16, said dial being supported upon the brackets 17 which project outwardly from one side of the frame 1.

I-lingedly secured to the outer end of the bar 14 is a trip member 18 having a downwardly projecting lug 19 formed at its inner end and movably arranged within the opening 20 adjacent its outer end. The lower end of the lug 19 is provided with a head member 21 which is adapted to engage the bar 14, and prevent the lug from being entirely withdrawn from the opening. The trip member 18 is yieldably held into spaced relation with the outer end of the bar let by means of a coil spring 22, which is disposed between the trip member and the outer end of the bar.

Rotatably mounted within the dial 16 is an indicator hand 23, said indicator being mounted upon the outer end of the shaft 24L and mounted upon the other end of the shaft is a suitable pulley 25, over which pass the hoisting ropes 26. From this it will be seen that as each bucketful of ore is raised from the mine, the indicator 23 will rotate around the dial l6, and as the bucket reaches the top of the shaft, the indicator 23 will strike against the lug 19, carrying the bar l t with it until the inclined portion of the trip member 18 engages with the edge of the end of the slot 26, thus pressing downwardly upon the trip member 18 and allowing the indicater to pass thereover. After the indicator has passed over the trip 18, the coil spring 12 will return the rod 9 and the bar 1 1 to their normal positions and the coil spring 22 returning the trip member 18 to its normal position. From this it will be seen that as the indicator 23 strikes the lug 19 and forces the bar 14 outwardly, the marking point 11 will mark upon the plate 3 the'exact time that the bucket was raised, each mark upon the plate indicating that one bucketful of ore has been raised from the mine or that a carload of ore has been taken from the mine.

From the above, it will be readily apparent that each carload or bucketful of ore is registered upon the plate 3 as it is taken from the mine. It will also be seen that should the hoisting mechanism stop, the marker 11 will remain stationary so that it will readily indicate the exact time the mechanism stopped and the time that it started so as to clearly indicate just how long the hoisting mechanism was idle. It will be seen that by having the marker arranged adjacent the periphery of the dial 5, it will readily indicate the exact time that each bucket of ore was taken from the mine. Thus it will be seen, on the drawings for a clearer illustration, that the hoisting mechanism started its operation at' 2 p. m. and worked steadily until 6 p. m., the dashes which extend at right angles to the main line on the marker indicate the various number of bucketsful hoisted from the mine.

From the above description taken in connection with the accompanying drawings, it will be readily apparent that I have provided a simple and durable recording instrument which will correctly record the various number of bucketsful of ore or carloads taken from the mine. It will also be apparent that should the hoisting mechanism remain idle, the instrument will correctly record the exact length of time that the meclr anism was idle. It will be also apparent that the device itself is extremely simple in construction and can be manufactured at a comparatively low cost.

lVhile I have shown and described the preferred form of my invention, it will be obvious that various changes in the details or" construction and in the proportions may be resorted to for successfully carrying my invention into practice without sacrificing any of the novel features or departing from the scope of the appended claims.
